This class implements all of the TableGen related functionality necessary for a language server...
LogicalResult runTableGenLSPServer(TableGenServer &server, JSONTransport &transport)
Run the main loop of the LSP server using the given TableGen server and transport.
Definition: LSPServer.cpp:188
This class represents an efficient way to signal success or failure.
Definition: LogicalResult.h:26
Encoding per the LSP specification, with mandatory Content-Length header.
Definition: Transport.h:41
static void setLogLevel(Level logLevel)
Set the severity level of the logger.
Definition: Logging.cpp:17
LogicalResult TableGenLspServerMain(int argc, char **argv)
Implementation for tools like tblgen-lsp-server.
static llvm::ManagedStatic< PassManagerOptions > options
Messages are delimited by a &#39;// --—&#39; line. Comment lines start with //.
Definition: Transport.h:43
A transport class that performs the JSON-RPC communication with the LSP client.
Definition: Transport.h:48
